Greenwood Silo’s goal for years has been to increase the efficiency and longevity of unloaders, and to reduce the problem areas. Listed below are areas that we have been focusing on to make our unloaders work better for you.
We observed the wear & tear on the unloader, as well as the occasional broken chain, that resulted from traditional hard-start motors. As a result, we developed the Greenline Drives which feature a soft-start, variable speed, VFD unloader control system. This system allows for more start-up torque than a single-phase motor, but does not put the chains and unloader through the shock that a hard-start does, and nearly eliminates any spike in electric use compared to a traditional hard-start motor.
